Fields 275 (SEC_ACT_1) and 276 (SEC_ACT_2)

Hello all,

We have a requirement to consume rates from data fields 275 and 276. We currently do not consume those fields into our application. In what conditions are 275 (SEC_ACT_1) and 276 (SEC_ACT_2) populated and 22 (BID) and 25 (ASK) not populated? Are both sets always populated or are the second activity fields only populated in some cases?
